Obstacle avoidance method and application of mobile obstacle avoidance safety system

Abstract

The invention discloses an obstacle avoidance method and application of a mobile obstacle avoidance safety system, the mobile obstacle avoidance safety system comprises an echo generation unit, a driving circuit unit, an echo detection circuit unit, an echo processing circuit unit and an alarm unit which are installed on an operation body, and the mobile obstacle avoidance safety system is started for many times in the moving process of the operation body. The echo generating unit emits and receives energy waves reflected by an obstacle and then sends echo signals to the echo detecting circuit unit, the echo detecting circuit unit amplifies the echo signals and then transmits the echo signals to the echo processing circuit unit, the echo processing circuit unit processes the amplified echo signals, and the echo processing circuit unit sends the processed echo signals to the control unit. And an alarm signal is sent to the alarm unit according to the processing result. According to the mobile obstacle avoidance safety system, the speed threshold value associated with the real-time distance between the obstacle and the operation body can be monitored, alarming, reminding or control operation is executed based on the relative speed between the operation body and the obstacle, and the obstacle avoidance method is more visual, safer, more reliable and more user-friendly.

Description

technical field [0001] The invention relates to a mobile obstacle avoidance safety system, in particular to a system comprising an echo generation unit, a drive circuit unit, an echo detection circuit unit, an echo processing circuit unit and an alarm unit, which can monitor obstacles and The present invention relates to an obstacle avoidance method and application of a mobile obstacle avoidance safety system based on speed thresholds associated with real-time distances between bodies. Background technique [0002] At present, most of the obstacle avoidance safety devices used in vehicles adopt the distance detection method. In this distance detection method, the obstacle avoidance safety device can only monitor the distance information between the obstacle and the running body for reminder or alarm, but cannot The real-time distance between the obstacle and the running body gives a corresponding early warning to the running speed of the running body, so the distance detecti...

[0002] At present, most of the obstacle avoidance safety devices used in vehicles adopt the distance detection method. In this distance detection method, the obstacle avoidance safety device can only monitor the distance information between the obstacle and the running body for reminder or alarm, but cannot The real-time distance between the obstacle and the running body gives a corresponding early warning to the running speed of the running body, so the distance detection method of the obstacle avoidance safety device has low intuitiveness and poor reliability
